The invention discloses a lavipeditum device which comprises a heating device. The heating device comprises a heat conducting element and further comprises a metal shielding layer which is electrically connected with a null line of an electric supply to reduce the potential difference between the heat conducting element and the ground. When the lavipeditum device is used, heat transfer is carried out on the heat conducting element and water, the metal shielding layer is arranged in the heating device of the lavipeditum device, the metal shielding layer is electrically connected with the null line of the electric supply to reduce the electromotive force of the heat conducting element so that the potential difference between the heat conducting element and the ground is effectively reduced, therefore, the potential difference between water heated by the heat conducting element and the ground is reduced. The using safety of the product is effectively improved, and the lavipeditum device is skillful in design, simple in structure and easy to implement.
Description
technical field [0001] The invention relates to the technical field of foot baths, in particular to a foot bath. Background technique [0002] Commercially available foot baths belong to the second category of electrical appliances in the safety standards of household appliances. They usually use double insulation or supplementary insulation, and there is no grounding requirement. However, due to the particularity of the use environment of the foot bath, when the foot bath is working, the induced electricity generated by the distributed capacitance formed by the heating device and water cannot be eliminated by grounding, resulting in the induction electricity acting on the human body during the use of the foot bath, causing the People feel numbness, and even tingling pain in severe cases, which brings great health and safety risks. Contents of the invention [0003] The main purpose of the present invention is to provide a foot bath that can effectively reduce the induced...
